Reading encoded query values
Decode percent-encoded text when you need to understand what a URL parameter actually contains.

URL Encoder & Decoder for Percent-Encoding and Readable URL Text
Characters such as spaces, symbols and non-Latin text do not always travel through URLs exactly as you typed them. URL encoding represents some characters with percent-based sequences; decoding turns those sequences back into readable text.
QUICK ANSWER
URL encoding converts characters into a URL-safe percent-encoded form, while URL decoding reverses that representation. For example, a space may appear as %20 in an encoded URL component. The SWS tool gives you a quick browser-based way to encode or decode text for troubleshooting, links and web work.
- Encode whenYou need text prepared for a URL component or query value.
- Decode whenYou need to read an encoded URL string in a human-friendly form.
- Be carefulA full URL and one URL component are not always encoded in exactly the same way.
WHEN IT IS USEFUL
Helpful when a URL contains characters that are hard to read or unsafe to pass literally
Most people meet URL encoding while debugging links, query strings, form values or copied browser addresses.
Preparing URL components
Encode text that will be inserted into a path, query value or other URL component where reserved characters may have special meaning.
Troubleshooting links
Compare encoded and decoded forms to spot spaces, punctuation, Unicode characters or delimiters that may be affecting a URL.
BEFORE YOU ENCODE
Know whether you are working with a complete URL or only one component
Do not encode blindly
Encoding an entire URL as though it were a single component can also encode characters that are part of normal URL syntax. Know what part you are preparing.
Keep reserved characters in mind
Characters such as ?, &, =, / and # have structural meaning in URLs. Whether they should be encoded depends on where the value sits.
Decode unfamiliar links cautiously
Decoding can make a URL easier to read, but it does not make an unknown destination trustworthy. Treat suspicious links as suspicious.
HOW IT WORKS
Encode or decode a URL value in a few seconds
Choose the direction you need, paste the text and review the result in context.
Open the encoder / decoder
Launch the Smart Web Solutions URL Encode and Decode Tool.
Paste the value
Add the URL, parameter value or encoded text you want to inspect or transform.
Choose encode or decode
Encode plain text for URL use, or decode percent-encoded text into a more readable form.
Review the result in context
Check that structural URL characters are handled correctly before placing the value into a live link, request or application.
Technical distinction: browser and programming APIs distinguish between encoding a complete URI and encoding one component. MDN notes that
encodeURIComponent() escapes more characters than encodeURI() because components and complete URLs have different needs.FREQUENTLY ASKED QUESTIONS
URL encoding and decoding questions
Short, direct answers for users, search engines and AI assistants.
What is URL encoding?
URL encoding, often called percent-encoding, represents certain characters using percent signs followed by hexadecimal values so the text can be used safely in URL contexts.
What does %20 mean in a URL?
%20 is the percent-encoded representation commonly used for a space character in URLs.
Is encodeURI the same as encodeURIComponent?
No. In JavaScript, encodeURIComponent escapes more characters because it is intended for individual URI components, while encodeURI preserves more characters that are meaningful in a complete URI.
Why would I decode a URL?
Decoding can make an encoded path or parameter easier to read and can help when debugging or checking what a link contains.
Can decoding tell me whether a URL is safe?
No. Decoding only changes representation. It does not verify the reputation, ownership or safety of the destination.
